Question

1. Th circuit below is that of a voltage divider with a voltmeter across R2. The internal resistance of the voltmeter is Rm=1??=1,000,000? R1 100 Vs 10V VM R2 100 Rm 1Meg VL voltmeter Resistance in Ohms a. Ignoring resistance Rm, find VL=VM = \frac{R2}{R1+R2} * Vs b. Include Resistor Rm and replace R2 with Req=Rm|| R2 and redraw the circuit. c. Find Voltage, VM(Meter Voltage) d. Replace R1 and R2 with 1?? resistors and repeat steps a - c e. Compare meter voltages of c and d, and compute %error= \frac{VMc-VMd}{VMc} * 100 f. Explain the difference
